CEMENT CLOSET-TANK.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed May 29. 1905. Serial No. 262,75

To all whom "it may concern:

Be it known that I, JosEPH A. WAsHICK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Cement Closet- Tanks, ofwhich the following is a specification.

This invention relates more particularly to a closet tank which isadapted to take the place of the ordinary tanks now in use, and todetails of construction and the means for mounting or supporting thesame. Its objects are to provide a closet tank which is adapted for usein warm climates and (lamp places where wood or metal would deteriorateor decay; and its further objects are to provide a sanitary tank whichwill not absorb water or leak, and to secure the flush pipe or otherpipes in the cement in a substantial manner.

This device is shown in the accompanying drawings in which:

Figure 1 is a front view. of a closet tank embodying this invention, a.part being broken away to show the details of construction, and, Fig. 2is an end elevation of the same showing the supporting brackets.

As shown in the drawings, this invention comprises a tank or receptacle3 of any desired form or shape adapted to be used for a closet tank.This receptacle is made of cement, concrete or the like and the wallsthereof are provided with a layer 4 of strengthening material such asmetallic screen, expanded metal, netting or the like.

The box or tank is preferably supported by means of metallic bands orstrips 5 which extend across the bot- .tom and up the sides and are bentover at the top edges of the side walls. These metallic strips may beembedded entirely within the concrete as indicated at the left hand sideof Fig. 2, or may be flush with the surface'as shown in Fig. 1, or lieagainst the surface as shown at the rearside of Fig, 2. These strips orbands may be further secured and held by means of clips or connections 6which extend in to engage with the metallic web 4.

Inorder to support the box or tank on suitable brackets such as shown at7, Fig. 2, the bands 5 are provided with projecting pins 8 which areadapted to engage with holes in the upper part of the bracket 7. Thesepins or projections may be threadedfor a nut 9 or may simply extend downthrough the holes of the brackets.

The flush pipe connection comprises a tube or pipe 10 having lateralflanges 11, 12 and 13. The first of the flanges engages with the topsurface of the bottom of the tank, and the second flange engages withthe metallic webbing and is embedded in the cement or concrete; whilethe third or bottom flange engages with the lower surface of the bottomof the tank and is preferably fiush therewith. The projecting end of thetube 10 is preferably tapered for a short distance and is provided witha lateral annular flange 14. The flush pipe proper 15 is adapted to beforced up over the conical end of the pipe 10, and over the annularflange 14 and to be hammered or forced in around the top of said flangeto make a tight connection. If desired, solder or the like may be usedas shown at 16 for further closing the joint. The siphon or otherflushing device may be connected with the pipe 10 in any desired manner.The water pipe is preferably arranged to enter at the top of the tank,or if desired, it can be extended up through the bottom and connected ina manner similar to the connection which I have described for the flushpipe.

It will be noted that with this form of construction and'with thematerial used, a sanitary closet tank is provided which is adapted towithstandall kinds of temperature and which will last 'for an indefinitetime, and, with the inside corners rounded as shown at 17, no places areleft in the tank for the accumulation of sediment or filth.

Having thus described my invention which I do not wish to limit to thedetails of construction, what I claim and desire to secure by LettersPatent is:

1. The combination of a concrete closet tank with supporting bands andpins' projecting from said bands and adapted to engage with suitablebrackets.

2. The combination of a concrete closet tank having metallicreinforcement in the walls thereof, a pipe connection having flangesengaging with said metallic reinforcement and with the upper and lowersurfaces of the bottom of said tank.

3. A cement closet tank, metallic supporting bands for said tank adaptedto engage with supporting brackets and a flush pipe connection havingflanges engaging with the upper and lower surfaces of the bottom of saidtank.
